How to Set Up LINE Social Login in WordPress [Step-by-Step Guide]

Social logins are now a common choice because users prefer signing in with accounts they already use instead of remembering new passwords.

Research shows that 69%of people abandon sign-up forms when they can’t recall their credentials.

As a WordPress website owner, adding social login options helps you streamline registration, improve user experience, and increase retention.

LINE has more than 170 million monthly active users and is especially popular in Japan and Thailand. Integrating LINE Login into your WordPress site simplifies authentication and gives your users a familiar, convenient login method.

Before we show you how to add LINE Social Login to your WordPress site, let’s see why it’s so important.

Why Should You Add LINE Social Login to WordPress?

Faster Registration for Users

Social login options like LINE let users sign in with a few clicks, removing the need to type credentials. This speeds up access and reduces friction during login.

Improved User Engagement

Providing multiple login choices increases the chance that users will complete registration. LINE users are especially likely to sign in when they can use their existing credentials, improving engagement.

Reduced Abandoned Signups

Long forms and new account requirements often cause users to abandon signups. With LINE login, you offer a faster, more convenient option that reduces abandoned registrations

Troubleshooting Common Problems with LINE Social Login

Running into issues with your LINE Social Login? Here’s a quick guide to troubleshoot and get everything back on track!

1. Invalid Redirect URI

Issue: The redirect URI in the LINE Developer Console doesn’t align with the one on your WordPress site.

Solution: Double-check that the Callback URL in both your WordPress settings and LINE Developer Console is identical, including the correct protocol (https://). Even a small mismatch can cause issues!

2. Login Not Working

Issue: Users can’t log in with LINE credentials.

Solution: Verify your Channel ID and Channel Secret. Make sure 2FA is enabled in the LINE Developer Console. Clear your browser cache and test again.

3. Profile Data Missing

Issue: Missing profile information, like name or email, after login.

Solution: Ensure the proper permissions and scopes are enabled in the LINE Developer Console to access user profile data. Clear any caching plugins that may interfere with profile data retrieval.

4. Plugin Conflicts

Issue: Other plugins conflict with LINE Social Login.

Solution: Disable all plugins except All In One Login, then reactivate them one by one to find the conflict. Make sure every plugin is updated.

5. Caching Issues

Issue: Caching can interfere with the display of the login button or the retrieval of user data.

Solution: Clear both your browser cache and server-side cache. To avoid conflicts, exclude login pages from caching or temporarily disable any caching plugins to test if that resolves the issue.
